Summerfest 2018's final weekend has competition for your attention. Here are some of the prime options in Milwaukee this weekend.

A new sound for 'Star Wars'

You can see the original "Star Wars" saga the way Oscar-winning composer John Williams heard it this weekend, by checking out the Milwaukee Symphony Orchestra's performance of "Star Wars: A New Hope" in concert, with a screening of the 1977 movie that started it all. The performances are 7:30 p.m. Friday and Saturday and 2:30 p.m. Sunday in Uihlein Hall at the Marcus Center for the Performing Arts, 929 N. Water St. Tickets range from $22 to $126.

Riverwest's secret gardens

It's your chance to see some lovely greenery you might not know existed. The Riverwest Secret Garden Tour, Sunday from noon to 4 p.m., gives you glimpses of some of the neighborhood's greenest spaces. Tickets, which include a walking map of the homes on the tour, are $5, and are available Sunday at the Riverwest Gardeners Market at N. Bremen and E. Locust streets. (After expenses, proceeds to go select Riverwest community projects.)

King Lear rules at Peck Pavilion

Milwaukee theater stalwart James Pickering plays one of Shakespeare's most captivating figures as the title character in "King Lear," this summer's Shakespeare in the Park entry courtesy the Optimist Theatre. The production begins this weekend at the Peck Pavilion outside the Marcus Center for the Performing Arts, with performances at 8 p.m. Thursday, Friday and Saturday, and 7:30 p.m. Sunday. (The production continues evenings July 12-15 and July 19-21, with a matinee on July 17.) Admission is free.

Up a caffeinated river

Start Sunday morning with a slug from the mug — and then a paddle down the river. The Urban Ecology Center hosts its first Coffee & Canoe session of the summer Sunday from 9 to 11:30 a.m. It starts, as all good mornings do, with coffee and other morning beverages and treats at the Milwaukee Rowing Club, 1900 N. Commerce St. And then, the oars go into the water. It's $25, $20 for Urban Ecology Center members. Registration at the center's website is recommended. (Future sessions are scheduled for July 22, Aug. 5 and Aug. 19.)

Karaoke for a cause

Here's a different kind of fundraiser: Woodland Pattern Book Center is hosting "Dedicated to the One I Love: Karaoke for Education," in which participants take the mic at a benefit for the Riverwest bookstore's youth arts programming and for Franklin Pierce Elementary School. The party starts at 7 p.m. Saturday at Woodland Pattern, 720 E. Locust St.

Different kind of balloon race

It's not your normal bounce house — The Great Inflatable Race is coming to Veterans Park, 1010 N. Lincoln Memorial Drive, Saturday from 9 a.m. to noon. Running more than a mile, the race is really more of an obstacle fun run, only the obstacles are ones you can bounce off of. It costs $75, with VIP packages, giving you access to more inflatable-climbing stuff, available for $90.

All-out competition in Pewaukee

The Pewaukee Triathlon, one of the longest-running such events in Wisconsin, returns Sunday, with seven swim-bike-run races starting at 6:15 a.m., Pewaukee Lake Beach, 203 W. Wisconsin Ave., Pewaukee. All of the registration slots have been filled, including those for the kids' triathlon starting at 7:30 a.m. Sunday — but that doesn't mean you can't watch and cheer them on. (There's also free swimming and transition clinics; check the website for details.)
